  1. Model 1 – unadjusted (raw) model
  2. Model 2 – model 2 was adjusted for age and body height
  3. Model 3 – model 3 was adjusted for model 2 and sedentary time
  4. CI confidence interval, LPA light physical activity, MVPA moderate-to-vigorous physical activity, VPA vigorous physical activity
  5. aValues were transformed to natural logarithms before analysis
  6. bβ gives the regression coefficient of the standardized values (Z-score) for each variable
